Should I apply to Engineering or Science for UCs?

@ucbalumnus true CS at SJSU is probably a reach -but, it looks like the OP expressed interest in more generic science and engineering major.

Last year anyhow, the rest of the STEM majors were within reach with and EI around 4600.

Of course - with the SAT suspension for Fall 21 - all of the impacted CSUs are wildcards next year.
